It has been a standing knowledge that Porsche has been planning to unveil the modified Boxster and Cuaman mid-engine sports cars at the Los Angeles Auto Show this week. But, Porsche made it official recently, even though it failed to provide any pictures, the German manufacturer revealed in its Spartan press release that "both cars will come with Porsche's new engine and transmission technology as well as many other significant technical and exterior refinements".

Besides some artistic modifications, the new 2009 Cayman coupe and Boxster roadster will show off extra powerful but also fuel-economical direct-injection engines with Porsche's new double-clutch PDK gearbox that made its introduction on the recently altered 911s.

For the very first time also at an auto show in the US, Porsche will showcase in Los Angeles the original car to bear the name "Porsche," the celebrated, 60-year-old mid-engine 356 which has come to be identified simply as 'Porsche No.1'. The company's LA Show display area will also highlight a Porsche 550 Spyder which is on loan from the special collection of Jerry Seinfeld.
